I replaced the 2 rear O2's and still get the same codes. |
P0158 says rich (rarely goes under 800mV), P0174 says lean, P1153 says not switching frequently enough.
Only bank 2, and brand new O2 did not help. Cats are only a few months old, GM replaced both under warranty.
Could this be a bad PCM? No idea what to do next. Replaced intake manifold gaskets, replaced PCV system.
Help would be appreciated.
